Question

the aluminium metal is corrosion resistant because of formation of oxide film which is​

Answer 1

Explanation:

It is resistant to corrosion due to 'passivation': the formation of a thin layer of aluminium oxide on the metal surface which prevents further oxidation. It is ductile and malleable at normal temperatures, making it easy to form. It is non-magnetic but is a good conductor of heat and electricity.

al+o2=al2o3.

hope it's helps..

Answer 2

Answer:

4Al + 3O₂ = 2Al₂O₃

It protects Al metal from corrosion.
